Indicator when there are extra reward for tank/heal role in LFG

[yuze]

Is there a way to give an alarm when LFG has extra reward for a role? I dont need to use lfg but when there is runes I am always up for it, but its not something I check all the time. Can a weakaura do this or something? Thanks
